You've heard 'em all, right? The obvious ones: "What's your sign?" The kind of funny ones: "Your daddy must be in jail, 'cause he stole the stars right outta the sky and put them in your eyes!" Even the plain old nasty ones: "Those pants look good on you, but they'd look even better. . . " Ugh. So we roll our eyes, ignore the poor chump or shoot a good one-liner back. Pickup lines never really work...or do they? Why would guys keep using them if they were never getting any results? Then the thought: Maybe guys use them because they've heard them from (gulp) girls? It's a terrible question, but we just had to find out. So we asked these five guys to tell us the best/worst/funniest pickup lines they've ever heard -- from a girl.

"I had a girl come up to me at a party, look at me really sincerely and say: "You've got really beautiful eyes." Then she just left. I didn't even have time to say thanks! I thought it was cool because I had to go track her down. It really made me want to find her." -- Trey, 20

"Once, a girl asked me if she had seen me in a movie before. As hard as it was not to lie about it, I didn't. But it was cool because it opened up a good conversation -- we started talking about movies and found out we like the same ones, and then we went on a date!" --Logan, 23

"One time I overheard a girl say to someone: "Do you believe in love at first sight, or do I need to walk by again?" That definitely caught my attention." --George, 21

"I hate pickup lines. Maybe girls can tell, because they never try them on me. But a girl asked my friend: "I lost my number -- could I get yours?" The line didn't work or anything, but we thought it was funny." --Kevin, 21
